Hello,
For a personnal transceiver using a bidirectionnal TX/RX superheterodyne architecture with a simgle FI (20, 28, or 54 MHZ SSB ladder filter)
made with severals modules availlables on eBay, alls these module are connectorised by SMA connector in order to test easely, and te expereiment differents boards for each modules:
SI5351 Board ( Adafruit or SV1AFN)
LNA HF 2N5109 Amplifier, (SV1AFN) (2N5109 2N3866 RF Amplifier PCB)
2N5109 Post mixer Amplifier, (SV1AFN) (2N5109 2N3866 RF Amplifier PCB)
SMA connectorised Diode Mixer, (RMS-11 5-1900MHz rf up and down)
Home made 20, 28 and 54MHZ ladder SSB quartz Filter (Fondamental AT cut)
FI amplifier board with 2XAD603 and 80dB AGC range (NEW AD603 80dB VCA voltage controlled gain amplifier module)
Microphone amplifier for DSB post mixer amplification,
Microphone amplifier used for DSB? generation
BF amplifier for loudspeaker (TDA2822M Mono Mini Amplifier Board Module)
I am looking for? ready made project with a SI5351 Generator providing:
OL, BFO, and the top would be the IF-SHIFT with a second incremental encoder WHO CAN CODE THIS!! please help!
ok course the SI5351 code should be able to have good Phase noise up to 160MHZ in order to be able to run on the 145MHZ Band, and then be user? for transverters.
?and push button choice should be availlable for OL + FI or OL - FI
for this project we should use a 4*20 LCD or az TFT in order to see a t the same time:
Rx frequency
OL Frequency
IF-SHIFT value
The BFO fr¨¦quency should be able to be changed by the menu very easely in order to test severals Ladders filters at diff¨¦rents frequency
I did use some sketch with very bad signal above 112.5MHz !! the SI5351 Registers should be? properly writen
-Please send me somme links
Regards, F4AER (French HAM)
